The goal is to create a "system update" wiki page under https://wiki.yoctoproject.org/wiki/Projects and on that page compare different possible update mechanisms. This issue is about setting up the page and explaining different criteria that are relevant (for example, resource consumption on device and server, integration with integrity protection mechanisms, availability, maturity, etc.).
Initial page exists, has useful content already, with more to come over time.
Checked the wiki page. quite useful
